The Nike Zoom TI is Nike's most innovative, women's-specific tennis shoe made close to the ground for the ultimate court performance. The upper is made of supportive rich leather, while the new, full-length Zoom Air™ is located in a soft Phylon™ midsole, which provides a great feel while on the court. The midsole also has a TPU ring around the bottom as a signature Zoom line. The outsole has regionalized wear zones with an XDR rubber compound and a full-length herringbone pattern that provides great traction on a variety of court surfaces.
